AM modulation with GUI (matlab)

有一学生成绩管理数据库如下表，要求建立一SAS数据集score，并输出显示 创建一个新的数据集class，新增平均成绩aver变量和等级考评grade变量，grade的值是根据aver值的大小给出A、B、C、D四个等级，并显示新数据集class(A student achievement management database as the table, called for the establishment of a SAS data set score, and output display create a new data set class, add an average score aver evaluation variables and grade level variables, grade values are based on the size of a aver value the A, B, C, D four grades, and displays the new data set of class)

ML法能够很好的估计信号的信噪比,GSM中GMSK调制信号的产生，小波包分析提取振动信号中的特征频率。( ML estimation method can be a good signal to noise ratio, GSM is GMSK modulation signal generation, Wavelet packet analysis to extract vibration signal characteristic frequency.)

基于JPDAF的多目标跟踪的仿真程序，以两个目标为例(JPDAF algorithm simulation program)

说明：  hurst指数估计 This function does dispersional analysis on a data series, then does a Matlab polyfit to a log-log plot to estimate the Hurst exponent of the series. This algorithm is far faster than a full-blown implementation of Hurst s algorithm. I got the idea from a 2000 PhD dissertation by Hendrik J Blok, and I make no guarantees whatsoever about the rigor of this approach or the accuracy of results. Use it at your own risk.
